I cannot get the two sets of data to match. In CoordTrans, if I enter eastings/northings as "UTM Zone 39N (WGS84)" and the lat/lon datum as "Pulkovo 1942", there is a distance of 96.34 metres between the coordinate.

I'm struggling to create a georeferenced AutoCAD drawing prepared from the data set and, ultimately, everything has to be in WGS84 for overlaying onto a chart.
